Which equation represents the data shown in the table below?
NU
15
2 3
31 1
4-1
5-3
y = -2.0 + 5
y = -2.0 + 7
y= 22 - 5
y= 2.-7

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
